'sAsH HOLDER George'R. Haynes, Danville, Va. ,t l, Application March 28, 1939, Serial No. 264,623

1 Claim.

This invention relates to a device for use in connection with'a window sash and it is designed vto support the sash inany position to which it may be moved and also to hold it against rattling and to press the sash tightly against the adjacent bead so as 'to obviate the necessity of utilizing weather-stripping. 'i

A further object is to provide a device. of this `,character which is simple'and compact in construction and .can be applied readily to a window sash.

A still further object is to provide a holder which is 'concealed while in use but to which access can be had readily for the purpose of effecting desired adjustments.

With the foregoing and other objects in view which will appear as the description proceeds, the invention .consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the nvention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figure 1 is a horizontal section through a portion of a window frame and sashes mounted therein, the said sashes being equipped with the present improvements. y

Figure 2 is an enlarged section on line 2 2, Figure l.

Figure 3 is a section on line 3 3, Figure 2.

Figure 4 is a section on line 4--ll, Figure 2.

Referring to the gures by characters of reference, A designates a portion of a window frame which is provided with the usual jamb stop B, parting bead C, and blind stop D. Portions of the upper and lower sashes mounted in the frame have been indicated at E and F respectively.

The holder constituting the present invention includes a box-like casing I the width of which is equal to the thickness of a sash. This casing is provided with a cover plate 2 having side flanges 3 insertible into the casing and when this .cover plate is properly located, it is adapted to lie flush with the side surface of the sash in which the holder is located.

The cover plate has an opening 3' in which is seated the head i of a screw 5 and this screw is extended through a tubular post 6 which extends from the bottom of casing I and is preferably made integral therewith.

A lever l formed preferably of sheet metal, is

pivotally mounted on the sleeve 6 and one end portionuthereof has a laterally extending stud 8 o-n which is mounted a roller 9 formed preferably of hard rubberv although other materials may be used. x i i l .f 55 .A longitudinalange I0 is lextendedlaterally from the-lever inwardly fromv the other end portion thereofl and this flange I0 is lprovided with an opening I I inwhich is loosely mounted an adjusting screw I2 having a head I3 seated in'ran w opening Iltinfonefside ofzlcasing I.r yA nut I5 is -engaged by screw l2 .and is adapted to Yslidevalong the bottom of casing i. interposed between this nut and the flange It is a cooled spring I6 which extends about the screw. y

The exposed face of -screw head I3 is constantly iiush with the outer surface of the wall in which it is located. The opposite `side wall of the casing has a slot Il located where the roller 9 can move thereinto when ilange I0 is subjected 20 to thrust by spring I6. Y v

The holder constituting the present invention is adapted to be sold as a complete unit. In practice the sash to be placed in the frame A is provided at each side at or adjacent to the 25- center thereof with a mortise I8 extending transversely therethrough7 the depth of this mortise being equal to the overall thickness of casing I and its cover 2 while the length of the mortise is equal to the overall length ofcasing I. 30 After the sash has been mortised, one of the present devices is placed in each of the recesses thus produced, the holder being so positioned that the slot I'l will be located'at the outer side of the sash so that roller 9 can thus thrust out- 35 wardly from the casing I. Each holder is secured in place by means of the screw 5 which serves also to fasten the cover 2 in position. After the sashes have been supplied with holders as described the upper sash Eis placed in the 40 frame A against blind strip D, parting bead C is then placed in the frame at each side, sash F is inserted in the frame, and stops B are secured in place. Before the sashesare thus placed, how# ever, the screws I2 in the holders are adjusted 45 to place springs I6 under desired tension, this tension being such as to force the rollers yieldingly against the adjacent strip or bead with suflicient force to hold the sashes against sliding movement .under their own weight. The 50 pressure of the rollers 9 against strip D and bead 3 will be such as to kpress the respective sashesinwardly, sash E being pressed against the parting bead C while the lower sash F is pressed inwardly against the stop B.. Because of the 55 tight t thus effected, it becomes unnecessary to use weather-stripping to keep out air. Furthermore 'the pressure exerted by the rollers against the adjacent surfaces will be such as to set up a' frictional contact between the sashes and the bead C and stop B respectively sufficient to overcome the weight of the sashes so that these sashes will be supported in any positions to which they may be moved. Obviously, also, by providingeach sash with one ofthese holders at each side thereof, the sash will be prevented from rattling. If, at any time, it should be found desirable to adjust the tension of spring I6, the stops B can be removed and this will expose the holders at the two sides of sash F and also expose the heads I3 of the screws l2. Thus the screws can be turned readily by means of a screw-driver to increase or reduce the tension of springs I6. The same result can be effected in connection with the upper sash E `simply by removing the parting bead C. Norymally, howevergthe holders are completely ooncealed betweenthe strips and bead.

' By providing each sash with holders such -as herein described it is possible to completely eliminate the ordinary counterbalance and cord and, by; making the; stop B and the parting bead C readily removable, the sashes can easily be re- -moved from the frame for the purpose of washing; glazing, etc.

r( The cost of installing the present improvements is `much vless than that of installing counterbalances.

The present improvements are also advantageous because they permit sufllcient clearance to be left between the sashes and the strip D and bead C respectively to allow for expansion due to changing climatic conditions and, therefore, the danger of the sashes becoming wedged in the frame is eliminated.

Where holders such as herein described are employed it is preferred to use lifts at the sides of each sash adjacent to the frame thereof a1- though thisfis not essential. v

What is claimed is: y

A window sash holder including a casing,

va cover plate mounted onl the casing, means extending through the lcover plate and casing for holding them together and to a sash, a lever fulcrumed in the casing for movement about said means, a roller carried by the lever, there being a slot in that side of the casing opposite to the bearing surface of the casing, an adjusting screw having a head exposed within and flush with said bearing surface, a nut slidable in the casing and supported and engaged by the screw, said nut being non-rotatably mounted with respect to the casing, a spring mounted on said screw and bearing against the nut, and means on the lever for receiving thrust from the spring, thereby to exert a thrust through the lever to the roller to project the roller through the slot and beyond that surface of the casing opposite to the bearing surface thereof.
